Abstract (en)
[origin: US10287135B1] Aspects of the disclosure relate to grabbing, holding and releasing an object including a pull stud. For instance, a grabbing mechanism may include a piston chamber having a piston configured to move within the piston chamber when the piston chamber is pressurized. The mechanism may also include a collet attached to the piston such that the collet and piston move together when the piston moves. The collet may include a groove. The mechanism may also include ball cage including a plurality of balls arranged at least partially within respective ball chambers of the ball cage. The ball cage may be arranged at least partially within the collet such that movement of the piston and collet causes the groove to align with the respective ball chambers. The plurality of balls may be configured to move into and out of the groove and to lock the pull stud within the mechanism.
